Title: Calender and an arrangement for fastening rolls of a calender
Inventor: KAARAKKA HEIKKI
IPC: D21G1/00
Filed: 2000-10-12
Abstract: A calender and an arrangement for mounting calender rolls, the calender comprising at least two calender nips (1, 2) formed by at least two stacked rolls (11 - 14). The rolls have bearing housings (3 - 6) by means of which the rolls (11 - 14) are stacked into roll pairs forming the calender nips (1, 2), and means (31, 32) connecting the bearing housings (3, 4 and 4, 5) of the rolls pairs with each other. At least two successive calender nips (1, 2) are arranged so that in the successive nips the mutual distance between the longitudinal axes of the lower rolls (12, 14) is smaller than the corresponding mutual distance between the respective upper rolls (11, 13) of the nips, whereby the disposition of the rolls (11 -14) forms a V-shaped angle as seen from the end of the calender machinery and thus forms an operating area between the nips for changing the rolls. The rolls are combined into nips advantageously using heatable pull rods inserted through the bearing housings.

Patent CA-2403619-A1 (CA)
Title: Ultra-capacitor based dynamically regulated charge pump power converter
Inventor: HANSEN PETER
IPC: H02M3/07
Filed: 2001-03-16
Abstract: A charge pump power converter efficiently provides electrical power by dynamically controlling a switch matrix of the charge pump that includes a flying ultra-capacitor CUF. Instead of open-loop oscillator-based control, a dynamic controller provides power upon demand by sensing the output voltage and changing the operating frequency of the charge pump in response. Moreover, this closed-loop dynamic control intrinsically voltage regulates the output voltage of the charge pump power converter without the inefficient addition of a step-down voltage regulator, downstream of the power converter. In addition, this closed-loop dynamic control allows for maintaining a desired output voltage even with variations in the input voltage. Further efficiency is achieved by controlling the charging and discharging of the flying ultra-capacitor CUF, both in rate of current change and in voltage ripple.

Title: Verifiable, secret shuffles of encrypted data, such as elgamal encrypteddata for secure multi-authority elections
Inventor: NEFF C ANDREW
IPC: H04L9/32
Filed: 2001-03-24
Abstract: A cryptographic process permits one to verifiably shuffle a series of input data elements. One or more authorities or individuals "shuffle", or "anonymize" the input data (e.g. public keys in discrete log form or ElGamal encrypted ballot data). The process includes a validity construction that prevents any one or more of the authorities or individuals from making any changes to the original data without being discovered by anyone auditing a resulting proof transcipt. The shuffling may be performed at various times. In the election example, the shuffling may be performed, e.g., after ballots are collected or during the registration, or ballot request phase of the election, thereby anonymizing the identities of the voters.
